Abstract

The real world is both a nonlinear and a noisy place - systems seldom respond linearly to the forces acting on themt and they are always subject to the random fluctuations (noise) of their surroundingst as well as to internal fluctuations of their own in many cases. The phenomena described here show how the signal to noise ratio can be enhanced by the inclusion of additional noiset and how chemical noise might provide a mechanism of protein transport in biological cells.
